regmap: Add bulk read/write callbacks into regmap_config

This one quite intrusive for the stable. Plus, at least "regmap: Add
missing map->bus check" is marked as fixing this one.

If there is no very good reason to include that regmap patch in stable
backports, I would skip it, it is a feature patch. Does any backport depend
on it ?

Well, yes and no.

Series of max310x patches depends on it:

!!a just a preparation; buggy, whole series for fixing this |ef8537927 285e76 o: 5.10| serial: max
310x: use regmap methods for SPI batch operations

...

!! whole series to fix corruption, which did not exist in 5.10 in the first place |57871c388 3f42b1 o: 5.10| serial: max310x: fix IO data corruption in batched
operations

But according to the 3f42b1, the bug did not exist in 5.10 in the
first place, so we got buggy 285e76 backported, and then fixes up-to
3f42b1 applied to fix it up.

Then probably both max30x patches should be dropped/reverted and the regmap bulk callbacks also dropped ?
